数字经济、交易效率与居民消费结构升级

数字经济是推动新发展格局形成、推进消费高质量发展的重要手段。从数字经济发展促进交易效率这一核心假定出发,基于分工模型将数字经济、交易效率与居民消费结构纳入统一框架分析理论机制,使用熵值法与主成分分析测度2005—2017年省级数字经济发展指数与交易效率对理论模型命题进行实证检验。数字经济发展程度每上升1%,居民消费结构升级指标上升0.087 4%,数字经济对居民消费结构的影响关系中,交易效率的中介效应为19.72%;内生性与稳健性检验验证实证结论稳健可靠。

Digital Economy, Transaction Efficiency and Upgrading of Resident Consumption Structure

Digital economy is an important means to deepen supply-side structural reform and promote high-quality consumption development. Based on the division of labor model, and the core assumption that the development of digital economy promotes transaction efficiency, the digital economy, transaction efficiency and resident consumption structure are integrated into a unified framework of theoretical analysis mechanism. Using entropy method and principal component analysis to measure the provincial digital economy development index and transaction efficiency from 2005 to 2017, the theoretical model was empirically tested. When the development degree of digital economy increases by 1%, the index of resident consumption structure upgrading increases by 0.087 4%. In the influence factors of digital economy on resident consumption structure, the intermediary effect of transaction efficiency is 19.72%. The endogeneity and robustness tests verify that the empirical conclusions are valid.
